Why do we need to write the client for WSDL files ?
You do not need to "write the client for WSDL files."
You can use a WSDL file to generate the client code for a web service. For example, the Net Express IDE has a feature called "Generate Client" which creates the COBOL code required to call a web service. All you need to do is submit the WSDL file and .... poof .... your client code is automatically generated for you. It takes about 1 to 3 seconds to create the client code.

From the above what i understood is :
We use wsdl files to generate the client on the fly with the help of tools.
Then we should use this generated client code to test the webservice by passing parameters to the methods?
Am i right?

A WSDL file contains a machine-readable description of a web service. You "can" use a WSDL file to generate client code that can be integrated into an application (service consumer).
The generated client code is integrated into the application which uses the web service at runtime. The application is then tested.
The generated code, by itself, is not enough to test the web service. You need to integrate the generated code into an application.
Once the generated code is in the application, then you can test the web service call.
Once this is tested, then the application can move into production.
This is one way in which to use a WSDL file to create an application that uses a web service. There are other dynamic methods that use WSDL to enable an application to use a web service.
The main point is that a WSDL file is much more than just a testing artifact.
